Janet prepared 15 kilograms of dough after working 3 hours. How much dough did Janet prepare if she worked for 4 hours?

20 kilograms

Step-by-step explanation:

15 divided by 3 is 5 so that is 5 kilograms a hour so just add another 5 kilograms and you get 20 kilograms

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

its 8
